Biennials usually flower at the second year of growth. Is it possible to make them flower in the first year itself? How?

Text Solution

Verified by Experts

Many biennials usually flower during second year of their growth. For flowering to take place, these plants should be exposed to cold season. Such plants could be made to flower without exposure to cold season in the first year itself, when they are treated with gibberellins.
